CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/CN2017/082806, filed on May 3, 2017, which claims priority to Chinese Patent Application No. 201610483728.3, filed on Jun. 28, 2016.

FIELD

On the market, the airflow passage of e-cigarettes does not directly enter the inside of atomizing head, but only passes through the top of the atomizing head, which can make the whole airflow more smooth, but also can cause the temperature difference between the top and the bottom of the atomizing head. When the temperature of the bottom and the top of the atomizing head is different, the liquid cotton at/close to the bottom of the atomizing head is easily burnt due to excessive temperature. In addition, when the atomizing head is not energized and heated, the pressure of the bottom of the atomizing head is reduced due to a sharp drop in the temperature thereof, which will cause the liquid absorbed on the liquid guiding member of the atomizing head to leak to the bottom to form an effusion.

The atomizing head sleeve 91 a is generally a tubular body open at both ends and includes a base 911 a and a tube portion 912 a provided on the base 911 a. A liquid inlet hole 913 a in communication with the liquid storage tube 50 is defined on the pipe wall of the tube portion 912 a, a vent 914 a in communication with the atomizing chamber 910 a is defined at the top of the tube portion 912 a.

The atomizing assembly 93 a is received in the atomizing chamber 910 a. the atomizing assembly 93 a includes a liquid guiding member 930 a, a heating element 932 a, and a fixing seat 934. The liquid guiding member 930 a is provided with a receiving hole 9301. The heating element 932 a is housed in the receiving hole 9301. The fixing base 934 is sleeved outside of the liquid guiding member 930 a and is provided with a liquid guiding groove 9341 in communication with the liquid inlet hole 913 a. In one embodiment, the receiving hole 9301 is perpendicular to the atomizing head sleeve 91 a.

In one embodiment, the atomizing assembly 93 a is received in the atomizing chamber 910 a in a direction perpendicular to the axis of the atomizing head sleeve 91 a. The liquid guiding member 930 a is a substantially semi-cylindrical body. The receiving hole 9301 is disposed along the axial direction of the liquid guiding member 930 a and extends through the opposite ends of the liquid guiding member 930 a. The axial direction of the receiving hole 9301 is perpendicular to the axial direction of the atomizing head sleeve 91 a. The heating element 932 a is a hollow cylindrical spiral heating wire open at both ends and is housed in the receiving hole 9301 in the axial direction of the receiving hole 9301. It can be understood that, in other embodiments, the heating element 932 a may also be a hollow heating pipe open at both ends. The fixing base 934 is a hollow semi-cylindrical shape engaging with the liquid guiding member 930 a and is sleeved outside of the liquid guiding member 930 a. The liquid guiding groove 9341 in communication with the liquid inlet hole 913 a is respectively defined at both ends of the fixing seat 934 in the radial direction thereof.

The separator 95 a is connected between the atomizing assembly 93 a and the air outlet pipe 37, and isolates the vent 914 a to form an air inlet 915 a and an air outlet 916 a on both sides of the atomizing assembly 93 a.

The air outlet pipe 37 defines an outlet passage 918 in communication with the air outlet 916 a and the mouthpiece connector 10. Thereby, the outside air enters the intake passage 917 from the passage between the adjustment groove 330 and the intake hole 310, to the air inlet 915 a, and to the inner cavity of the heating element 932 a via the opening of one end of the heating element 932 a. Then, the outside air is sufficiently mixed with the smoke, and sequentially flows out from the opposite end of the heating element 932 a, the air outlet 916 a, the outlet passage 918 a, and the mouthpiece connector 10 for the user to inhale. Since the outside air flows through the entire inner cavity of the Heating element 932 a, on the one hand, the outside air can take all the smoke out to prevent the smoke from being liquefied and formed into an effusion after the atomizer 100 is stopped. On the other hand, the temperature distribution of the inner cavity of the heating element 932 a is uniform, without local overheating, and further, the leakage of the smoke liquid adsorbed by the liquid guiding member 930 a due to the sudden drop in temperature and the sudden drop in pressure is prevented from forming effusions.

The air inlet 915 a and the air outlet 916 a has a semicircular cross-section, respectively. The cross section of the air outlet pipe 37 is a semicircular shape matching the air outlet 916 a, and one end of the separator 95 a with respect to the fixing seat 934 abuts against the air outlet pipe 37. The air inlet 915 a and the air outlet 916 a are in communication with each other through the inner cavity of the heating element 932 a, so that the outside airflow passes from the intake hole 310, the intake passage 917, and the air inlet 915 a successively, to the inner cavity of the heating element 932 a in the lateral direction, and then flowing out through the air outlet 916 a, the outlet passage 918 and the mouthpiece connector 10 successively.

The air inlet 915 b and the air outlet 916 b are in communication with each other through the bottom of the outer periphery of the heating element 932 b. The external airflow passes from the air inlet 915 b, to the bottom along the top of one side of the outer circumference of the heating element 932 b, and to the top along the bottom of the other side of the outer periphery of the heating element 932 b, then flows out through the air outlet 916 b. Thus, the external airflow can flow through the entire heating element 932 b in the atomizing chamber 910 b, thereby reducing the temperature difference and avoiding effusion problems. Further, the outside air can bring all the smoke out, to prevent the smoke from returning to the liquid state and forming effusions after the atomizer 100 is stopped.

In the embodiment, the heating element 932 c is a hollow cylindrical spiral heating wire that is open at two ends. The heating element 932 c is axially sleeved in the liquid guiding member 930 c along the liquid guiding member 930 c and abuts against the inner wall of the liquid guiding member 930 c. It can be understood that, in other embodiments, the heating element 932 c can also be a hollow cylindrical tube with an opening at two ends.

The separator 95 c is substantially a T-shaped plate. The wider end of the separator 95 c is supported on the tube portion 912 c, and is inserted into the notch 920 c and the receiving groove 919 c.

The narrower end of the separator 95 c is inserted into the heating element parallelly along the axial direction of the liquid guiding member 930 c, to isolate the vent 914 c to form the air inlet 915 c and the air outlet 916 c. The air inlet 915 c and the air outlet 916 c communicate with each other through the bottom of the inner cavity of the heating element 932 c. The external airflow flows in through the air inlet 915 c, to the bottom along the top of the inner side of the heating element 932 c, and to the top along the bottom of the other side of the heating element 932 c and flows out through the air outlet 916 c.

In the present disclosure, the vents 914 a/b/c of the atomizing heads 90 a/b/c are separated by the separators 95 a/b/c to form the air inlet 915 a/b/c and the air outlet 916 a/b/c. The air inlet 915 a/b/c and the air outlet 916 a/b/c are in communication with each other through the inside chamber, the inner bottom or the outer bottom of the heating elements 932 a/b/c in the atomizing assemblies 93 a/b/c. Thereby, when the outside air enters, the external airflow can across through or flow through the entire heating element 932 a/b/c in the atomizing chamber 910 c, thereby reducing the temperature difference and avoiding effusion problems. Further, the outside air can bring all the smoke out, to prevent the smoke from returning to the liquid state and forming effusions after the atomizer 100 is stopped.
